Application filed March 17, 1905. Serial No. 250,535.

To all whmn it puny concern:

Be it known that I, BENJAMIN F. FIsHER, a citizen of the United States, residing at Steubenville, in the county of Jefferson and State of Ohio, have invented certain new and useful Improvements in Grease-Compression Cups; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form. a part of this specification.

My invention relates to a new and useful improvement in grease-compression cups cmploying a gravityweight to force the con.- tents of the reservoir into the supply-line leading to the different parts of the engine to be lubricated.

In the accompanying drawings, forming a part of this specification, I have illustrated my invention by several views.

Figure l is a vertical sectional View of the cup and gravity-weight portions of my device. Fig. 2 is a view of the compressionweight. Fig. 3 is an inverted View of the upper section of said weight. Fig. 4 is a top plan view of the lower section of said weight, and Fig. 5 is an edge and top view of one of the creepers used in connection with the compression-weight.

Numerals of reference designate like parts throughout the several views, in which- The numeral 1 represents the reservoir or grease-receptacle of my cup, 2 the securing threaded lower portion of the same, and 3 a screw-valve regulating the flow of grease from the reservoir through a channel 4, formed in the securing-stem 2.

Operatively seated in the reservoir portion 1 is a gravity compression-weight consisting of an upper portion 5 and a lower removable section. 6, held in position by set-screws 7 7. Formed in the center of the bottom face of the upper section 5 is a radial out groove 8, and on the upper face of the bottom section 6 is a flat groove 9, cut across the center to any desired size or depth. These two grooves are adapted to register with each other when the two sections of the weight are united and together form a seat for a pair of creepers 10 10. These latter members are made of flat pieces of spring-steel or any other suitable metal and are bent to curve u ward at one end, while in the other end is "ormed a hole to fit over the head of a tension-pin 11. This latter pin passes down through the center of the upper section 5 and is threaded on the top to meet a thumb-nut 12, and in the lower end is a head portion 13, which tapers down to meet the straight shank portion, said head being of sul'licient size to enter the holes formed in the creepers 10 10. In the center of the groove 9 is a recess 14 large enough to receive the head of the tension-pin 11. Formed around the lower section 6 is a groove in which is placed a packing-ring 15.

After the reservoir portion has been. supplied. with grease the compression-weight, as shown in Fig. 2, is inserted on top of the lubricant. Then by simply tightening up on the thumb-nut 12 on top of the weight it will draw up the tension-pin. 1 1. and force out the creepers until the head portion of said pin fills the holes formed in said creepers and causes the ends of the same to engage against the wall. of the reservoir. The vibration of the engine or the centrifugal force produced by the cup being placed on. a crank-pin will compel the creepers to operate and force the weight down against the body of grease and at the same time by reason of their friction hold on the reservoir-walls prevent the weight from being thrown out of its seat in the cup. An even and steady feed of grease is thus assured, the exact amount necessary for the needs of the engine being regulated by the valve 3.

In. order to release the friction-contact for the purpose of removing the compressionweight, loosen the thumb-screw 12 and push down on the tension-pin. This will cause the head portion to enter the recess 14, and the creepers will close in on the taper part of the shank, so that the weight can be lifted out. The removable lower portion of the weight affords a ready means of inserting the tension-pin and adjusting or replacing the creepers.

Having thus fully shown and described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a grease-compression cup of the character described, the combination With a reservoir portion, of a compression-weight operatively seated in the same and having a removable lower portion in the upper face of which is formed a channel adapted to register with a radial cut groove formed in the up per portion of said weight; a screw-regulated tension-pin passing down through the upper portion of said weight, the lower end tapering outward forming a head; a pair of frictioncreepers seated in the groove formed by the upper and lower sections having openings therein adapted to fit over the head portion of said tension-pin; and means of depressing the tension-pin to draw the creepers clear of the reservoir-wall; as and for the purpose set forth.

2. In a device of the character described, a suitable cup, a compression-weight Working therein, said weight having passage-ways, creepers movable longitudinally of the passage-ways to engage the wall of the cup, and means carried by the weight to hold said creepers against movement.

3. In a device of the character described, a suitable cup, a compression-Weight working therein having passage-Ways, creepers movable in the p assage-ways longitudinally thereof, and means carried by the weight for moving said creepers in one direction and holding them against movement in the opposite direction.

4. In a device of the character described, a suitable cup, a compression-weight working therein, said weight having radial passageways, creepers movable longitudinally of the passage\vays means for moving said creepers in one direction and means for holding said creepers against movement.

5. In a device of the character described, a suitable cup, a compression-weight therein having passage-ways, creepers movable longitudinally of the passage-Ways, said creepers having overlapping ends, provided with registering apertures, and means passing through the apertures for moving the creepers in one direction.

6. In a device of the character described, a suitable cup, a compression-weight therein having passage-Ways, creepers movable longitudinally of the passage-ways, said creepers having overlapping ends, provided With registering apertures, and means passing through the apertures for moving the creepers in one direction, said means also holding the creepers against movement in the oppo site direction.

7 In a device of the character described, a suitable cup, a compression-weight working therein having passage-Ways, a tension-pin working within the weight and communicating with the passage-ways, said pin having an end tapered to form a head, and creepers movable longitudinally of the passage-ways, said creepers being provided with apertures through which the tension-pin passes the walls of the apertures being engaged by the tapered head of the pin.

8. In a device of the character described, a suitable cup, a compression-weight therein having passage-Ways, a tension-pin movable through the weight and intercepting the passage-ways, creepers movable longitudinally of the passageways, said creepers being engaged at one end by the tension-pin to move said creepers in one direction and hold them against movement in the opposite direction.

9. In a device of the character described, a suitable cup, a compression-weight therein formed in sections, the opposing faces of the said sections having registering grooves forming passage-ways, means for holding the sections together, and creepers movable within the passage-ways.

10. In a device of the character described, a suitable cup, a compression-Weight therein having passage-Ways, a tension-pin movable in the Weight and intercepting the passageways, said passage-ways having a depression at a point beneath the tension-pin, and creepers within the passage-ways operatively controlled by the pin.

11. In a device of the character described, a suitable cup, a compression-weight within the cup having passage-Ways, creepers movable within the passage-ways, and a tensionpin movable Within the weight and intercepting the passage-Ways, said pin engaging the creepers in such a way that movement of the pin in one direction imparts movement to the creepers in one direction longitudinally of the passage-ways, and holds said creepers against movement in the opposite direction.

In testimony whereof I afliX my signature in presence of two witnesses.
